Y.. a corporation of New York Application April 10,1940, serial No. 328.844 z claims. (ci. 13s-25) 'I'his invention relates to folding umbrellas, and more particularly to the telescopic stick therefor.

The present application is a continuation in 5 part of my co-pending application Serial Number 284,580. Y

The primary object of my invention is to generally improve folding umbrellas. A more particular object is to improve the telescopic uml0 `brella stick used with such umbrellas.

V vStill another object of my invention is to improve the ease and convenience of operating a folding umbrella. It is customary to provide the handle of the umbrella with a skirt which ts around the tips oi the ribs in order'to hold the ribs bunched around the stick when the umbrella is closed but left in extended condition'. Heretofore, the handle Was made axially reciprocable for a short distance relative to the end of the stick, and was provided with a pull spring within the stick for normally pulling the handle over the tips of the ribs. Such an arrangement is shown in my Patent 2,177,458 issued October 24, 1939. A further object of my invention is to make the operation of the umbrella more convenient by eliminating the aforesaid spring action and substituting mechanism whereby the handle, when pulled outwardly, will remain outwardly, yet when pushed inwardly to engage the rib tips will remain inwardly, thus holding the umbrella in closed condition. v

Still another object is to simplify the attachment of the `handle to the stick, making possible an inexpensive fixed screw mounting, the desired movement of the handle to engage or release the rib tips being obtained by relative movement of the two telescopic parts of the stick, instead of by movement of the handle itself relative to the stick. For this purpose the telescopic parts of the stick are provided with detent means adapted to hold the stick in either of two positions when extended, one of these positions being such that the rib tips are free of the handle, and the other being such that the rib tips are received within and confined by the handle.

.In accordance with still another object of the invention, a part of such detent means may also be employed to hold the telescopic parts of the stick in a third position, namely, the shortened 5o or telescoped position after the umbrella has been folded. At this time the skirt of the handle may be used to'receive and corinne the folded ribs at the hinges thereof.

To the accomplishment of the foregoing, and` other more specific objects which will hereinafter appear, my invention consists in the umbrella elements, and their relation one to the other, `as hereinafter are more particularly described in the specification and sought to be defined in the claims. The specification is accompanied by l drawings, in which:

Fig. -4 is a section similar to Fig. 1, but with the handle raised to engage the rib tips;

Fig. 5 is a horizontal section through the um- 20 brella stick taken in the plane of the line 5-5 of Fig. 4;

Fig. 6 is a section through the umbrella in folded condition;

Fig. 7 is an elevation of the normally concealed 2l upper or inner end of the lower or inner member of the umbrella stick;

Fig. 8 is a section, similar to Fig. 6, but taken through a modified form of the invention; and

Fig. 9 is a section, similar to Fig. 4, but showa0 ing the said modication.

Referring to the drawings, and more particularly to Fig. 6, the umbrella comprises a telescopic stick including tubular members I2 and I4 slidable one within the other, and folding ribs made up of upper ribs I6 and lower ribs I8 hinged at 20. These ribs may be of the double spring wire type disclosed and claimed in my aforesaid Patent No. 2,177,458. The upper ends of ribsl IBare pivotally secured on a rib retainer 0 22, which in turn is iixedly mounted at the upper end of the umbrella stock. The ribs are adapted to be spread apart by appropriate spreaders 24, the upper ends of which are pivotally connected to ribs I6 at 26, and the lower 45 ends of which are pivotally connected at 28 to a runner 30,which is slldablev on the umbrella stick. A catch 32 ls-provided on the outer tube I2 of the stick to receive and hold the runner when the umbrella is spread. A handle 3l is secured to the lower end of the inner tube Il of the stick, this handle preferably being provided with a skirt 3l, adapted to receive and hold the ribs, whether the umbrella is in folded condition as shown in Fig. 6, or in extended condition as il shown in Fig. 4. With the umbrella in extended condition, as in Fig. 4, it is the ornamental tips 38 of the ribs that are received within the skirt 36. With the umbrella in the folded condition of Fig. 6, it is the hinge extensions 40 of the ribs that are received within skirt 36.

Referring to Fig. 6, the umbrella stick is held in telescoped condition by appropriate detent means. Specifically thelower or inner member I4 is provided with one or more balls 42. It is preferable to use two such balls, and they are normally spread apart or urged outwardly by a compression spring 44 disposed therebetween. The upper or larger diameter member I2 of the stick is internally grooved at 46 to provide a ledge to receive the balls 42, and the groove 46 is so located as to receive the balls when the stick has been telescoped to its full extent with the rib hinges received within the handle. It will be evident that although the stick tends to remain in telescoped position, it may, nevertheless, be extended by simply pulling the handle 34, and with it the inner member I4, downwardly with enough force to overcome the resistance of the detent balls 42.

The groove 46 is preferably formed by channeling the metal of tube I2 outwardly, thus also forming a bead 48 on the outside of the tube. Bead 48 may be utilized to positively locate the rib retainer 22 against downward movement. For this purpose, the lower end of the rib retainer is cut to a diameter somewhat larger than the tube I2, and large enough to be forced over bead 48. The rib retainer may then be driven downwardly over the upper end of tube I2 until it comes to a positive stop against the bead 48. The interior of the retainer 22 may be axially fiuted or serrated, so that the metal bites into the wall of tube I2, thus locking the parts together against relative rotation. The upper end of tube I2 is flared outwardly against the upper end of the retainer, as is indicated at 50, thereby holding the retainer against upward movement. In this way, the retainer is locked in l,position against movement in any direction. The cap 52 may be conventional, and is threadedly received on the rib retainer after the fabric covering has been applied to the umbrella.

The detent balls 42 may also be used to nx one of the extended positions of the umbrella. stick. Thus, referring to Fig. 4, the inner or lower tube I4 has been partially pulled out of the outer or upper tube I2, though not to its maximum extended condition. It is perhaps a half inch shorter than the maximum, this difference being used to cause the skirt 36 of handle 34 to engage and confine the rib tips 38, the ribs being at this time in extended condition, with the parts I8 in alignment with the parts I6. The handle 34 is held against upward movement by the rib tips 38. The upper tube I 2 is provided with means 54 to engage the detent balls 42, thus holding the handle against downward movement.

The means in this case is a ledge 54 formed by the upper end of a sleeve which is pushed into and forms a permanent part of the tube I2. The sleeve is preferably recessed or slotted at 56, and the outside of tube I2 may bevincised at 58 to form sharp positive stops which are received in a plurality, say, four notches 82 adapted to receive a lock 64. The lock 64 is resiliently mounted within tube I4, and may be manually pressed inwardly to telescope the stick, but this is ordinarily not necessary for reasons subsequently explained. The engagement of lock 64 with one of the notches 62, not only holds the stick in its fully extended position, as shown in Figs. 1 and 2, but also prevents relative rotation of the upper and lower parts of the stick.

The sleeve 54 serves an additional function in acting as a bearing for the lower tube I4 of the umbrella stick. It is customary to make the upper and lower tubes substantially different in diameter, in order to provide ample clearance therebetween. Heretofore, it has been the practice to roll or draw the lower end of tube I2 inwardly to a smaller diameter -in order to provide a sliding bearing for tube I4. A finishing ring for notches 62 was then applied over the outside of tube I2. With the present construction, the lower end of tube I2 may be left uniform in diameter, thus reducing its cost, and the internal sleeve 54 acts as an excellent bearing for the inner tube I4.

When it is desired to release the ribs, in order to open or spread the umbrella, the handle 34 is pulled downwardly from the position of Fig. 4 to the position of Fig. 1. At this time the detent balls 42 are forced inwardly and ride within the sleeve 54. When the handle is moved to lowermost position, the lock 64 springs out into one of the notches 62, and acts as a detent, tending to hold the handle in lowermost position. It will be understood that in the position of Fig. 4, the lock 64 is compressed inwardly, and is held within the sleeve 54.

The outward movement of handle 34, that is, the maximum extension of the telescopic stick, is limited by a ledge or flange 'I0 formed at the upper end of tube I4. This bears against the inner end of sleeve 54, and positively prevents the inner member I4 from being pulled entirely out of the upper tube I2. The flange 'I0 is preferably formed as a part of a cap 12, which is desirably given a conical configuration. This is desirable in order to move readily past any obstructions which may be in the way, as, for example, if the catch 32 (Fig. 6) is deformed inwardly. Moreover, the cap 'I2 is preferably formed with a cylindrical or plug-like portion 'I4 which is driven into the upper end of tube I4. The plug and cap assembly is held in place not only because of its tight t, but preferably also by using a pin 16 which is driven through tube I4 and the cap.

The plug portion I4 of the cap is drilled witha hole extending diametrically therethrough, and freely receiving the detent balls 42 and the spring 44 therebetween. In this Way, a solid tubular passage is provided across the upper end of the member I4 for the detent balls and spring.

The metal of tube I4 around the ball 42 is pref- Fig. 1, it rides over the lock 64 and presses the same partially inward. The latch is moved in enough so that it acts merely as a spring detent, rather than as a positive lock. In other words,

if handle 34 is pushed forcibly upwardly the lock 64 is cammed inwardly, and the stick may be telescoped. However, when the runner 80 is pushed upwardly to spread the umbrella, it rides 5 o the lock 64, which then springs outwardly further than is shown in Fig. 1, to a position such as that shown in Fig. 2, and at this time the locking action is positive, so that the umbrella stick cannot accidentally telescope while l0 using the umbrella.

'To assemble the umbrella stick the rib retainer 22 is permanently afllxed to the upper end of the outer tube |2, and the sleeve 64 is permanently fixed in the lower end of tube l2, as

1'5 was previously described. The inner tube I4.

after being tted with the -cap 12 and the detent balls 42, is dropped downwardly through the outer tube I2. The handle 34 is then screwed on to the lower end of said inner tube I4. The

screw threaded cap 52 may then be applied to the rib retainer, but is preferably applied only after the fabric has been added to the umbrella.

A modified form of the invention is shown in Figs. 8 and 9 of the drawings. In this case,

instead of using a single pair of balls on the lowerstick for cooperation with two different ledges in the upper stick, I employ two pairs of balls in the lower stick which cooperate with 3o a single ledge in the upper stick. Specifically,

the lower stick 80 (Figs. 8 and 9) is provided not only with the spring-pressed balls 82 near the upper end of the stick, but also another pair of spring-pressed balls 84 near the lower end of the stick. The lower balls 84 are so located as to cooperate with the ledge formed by the upper end of the inserted sleeve previously referred to, said sleeve being here numbered 86. With the umbrella in extended condition, the

operationis exactly as previously described, forthen it is the upper balls 82 which cooperate with the sleeve 86. This is clearly shown in Fig. 9, in which the umbrella is assumed closed while in extended condition, the ornamental rib tips 88 being received in the skirt 90 of handle 92. It will be understood that the tips may be released, preparatory to opening the umbrella, by pulling handle 92 downwardly until the flange 94 at the top of inner stick 80 reaches sleeve 86.

The parts will then be in a relation corresponding to that shown in Fig. 1.

When the present umbrella is folded, as shown in Fig. 8, the upper balls 82 serve no useful function, but the lower balls 84 come into action.

When the rib hinge extensions 96 are received within handle skirt 90, the balls 84 reach the upper end of sleeve 86, thereby holdingthe parts in the closed relation shown in Fig. 8.

One advantage of the modification shown in Figs. 8 and 9 is in eliminating the need for the upper ledge or groove 46 of Fig. 1. It is a rather expensive operation to form this groove, and in my own manufacturing experience, I find that it is less expensive to add the second pair of detent balls than to form a groove in the outer tube.

The inner and outer tubes are both left in simple straight (uniform diameter) condition.

An additional advantage of the modication shown in Figs. 8 and 9 is that a soft aluminum material may be used for the inner and outer tubes. The inserted sleeve 86 is made of brass or like relatively hard material, and will not wear out quickly. If the groove 46 (Fig. 1) is used, diiiiculty may result if the tube is made of spring |04 compressed therebetween.

soft aluminum because the groove may wear and lose its holding action.

In the modification of Figs. 8.and 9 there is no outwardly projecting bead to limit downward movement of the rib retainer 98. However, this 5 is no serious disadvantage, and simply restores the present-day conventional practice, in accordance with which the rib retainer is merely driven with a force t over the upper end of the outer tube. The retainer is preferably ax- 1'0 ially iiuted, and is held against downward movement by its force ilt, and by the ilutings. The retainer is held against upward movement by spinning the upper end oi the tube outwardly.

The lower detent balls 84 are supportedmuch 15 as in the case of the upper detent balls, a piece of brass rod |00 being driven into the lower end of tube 80, and locked in position, as by means of a pin |02. A hole is drilled diametrically through the tube and inserted rod, thus forming 20 a continuous passage for the balls 84 and a The metal of tube around `balls 84 is preferably excised or spun inwardly slightly to prevent escape of the balls. while at the same time permitting partial 85 projection of the balls for the desired detent action.

The lower end of the inserted rodV |00 is preferably threaded, as shown at |06, to threadedly receive the handle 92. There is a slight advan- 30 tage in this construction over that shown in Fig.

4, in that the threaded hole in the handle may be made of currently standard size, instead of being made larger as is required when screwing the handle directly on the tube, as shown in 85 Fig. 4.

It will be understood that the top insert or plug ||4 (Figs. 8 and 9) is also made of brass or like moderately hard metal. If the umbrella stick is forcibly extended, no injury results, for 40 the blow is taken by the brass flange striking the brass sleeve 86. Brass, while softer than the tempered spring steel wire used for the ribs (in accordance with my Patent 2,177,458), is quite hard compared to the aluminum tubing used for 45 the umbrella stick. f

In Fig. 8 the runner |08 is shown provided with a tubular linger-piece ||0 which is slidable for a short distance on the runner, this tubular vfinger-piece having sloping or frustro-conical 50 -The stick is provided with appropriate spring detent means establishing three different positions of the stick; one for the folded umbrella, and two for the extended umbrella. The latter 65 two positions are such as to either hold or release the rib tips, according to whether the umbrella is to be left closed or spread, all while in ex` tended condition. There is no need to continue holding the handle outwardly against a spring, 7o with consequent annoyance and confusion. After the position of the handle has been changed,l the two hands of the operator may be used to appropriately gather or spread the umbrella ribs.

From the standpoint of manufacture, the new 75 structure has the advantage of eliminating a circular spring, previously needed inside the umbrella handle to hold the umbrella in telescoped position. It further eliminates a pull spring with associated brass sleeve and holding pins previously needed for slidably mounting the handle at the lower end of the stick. It is unnecessary to draw the lower end of the outer tube inwardly to a smaller diameter, and instead both tubes may be of uniform diameter, a sleeve being used to nish and protect the tube, and to cooperate with spring detents. The tubes may be made of soft metal because the detent parts which ride against the inside of the upper tube are smooth, round balls which do not scratch or wear the inside of the tube, and even more important, the parts of the complete stick which are subject to wear are made of relatively hard material. The inner end of the smaller tube is so capped as to provide a strong ledge or flange to limit extension of the stick, and to further provide a solid guide hole for the detent balls and spring, and also to provide a conical cap for the end of the tube.

It will be apparent that while I have shown and described my invention in a preferred form, many changes and modifications may be made in the structure disclosed without departing from the spirit of the invention, as sought to be defined in the following claims.
